CONSTITUTION:The objective composition contains (A) 5-70wt.% (preferably 10-40wt.%) of a surfactant preferably consisting of an alkylbenzene sulfonate salt, alkylether sulfate salt, olefin sulfonate salt, alkane sulfonate salt or polyoxyethylene alkyl(phenyl) ether and (B) 0.05-5wt.% (preferably 0.1-3wt.%) of an amino-modified silicone amide compound having a 7-24C acyl group (which may have a polyoxyethylene chain therein) at the N terminal of the amino- modified silicone as a substituent.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a detergent assembly, and more particularly to a lightweight detergent assembly with excellent clothing shrinkage prevention properties (felt shrinkage prevention properties). [Prior art and its problems] Delicate clothing such as wool products and silk products are washed by hand using light detergents or by applying weak mechanical force to avoid damaging the fabric. However, it is a common daily experience that among these types of clothing, wool products in particular have a tendency to shrink (felt shrinkage) even when careful care is taken, such as gently rubbing or washing them in lukewarm water. First, the present inventors discovered that particles having a cationic group or a tertiary amino group have a particle size of o. It has been found that a light detergent containing a fine polymer latex with a particle size of 0.00 to 0.2 is extremely effective in preventing felt shrinkage (Japanese Unexamined Patent Publication Nos. 8492-1984 and 89596-1983). However, manufacturing such fine polymer latex requires special manufacturing conditions, which is industrially disadvantageous. [Means for Solving the Problem] As a result of intensive research into base materials that can replace polymer latex, the present inventors have discovered that a cleaning agent containing a certain type of silicone compound has an excellent effect of preventing felt shrinkage. The present invention has now been completed. That is, the present invention includes (a) surfactant 5 to 70% by weight
(b) An amino-modified silicone in which an acyl group having 7 to 24 carbon atoms (which may have a polyoxyethylene chain in the acyl group chain) is bonded to the terminal nitrogen atom of the amino-modified silicone as a substituent. The present invention provides a detergent composition containing 0.05 to 5% by weight of ξdide.

Surfactant (a) used as main cleaning base in the present invention
The conventionally commonly used hydrophobic group has 8 to 2 carbon atoms.
For example, anionic surfactants include linear or branched alkylbenzene sulfonates, alkyl or alkenyl ether sulfates, alkyl or alkenyl sulfates, olefin sulfonates, alkanesulfonates, Examples include α-sulfo fatty acid salts or esters, saturated or unsaturated fatty acid salts, alkyl or alkenyl ether carponates, amino acid type surfactants, N-acylamino acid type surfactants, alkyl or alkenyl phosphate esters or their salts, etc. It will be done. Examples of amphoteric surfactants include carboxy or sulfobetaine type surfactants, and examples of nonionic surfactants include polyoxyalkylene alkyl or alkenyl ethers, polyoxyethylene alkylphenyl ethers, higher fatty acid alkanolamides, and the like. Examples include alkylene oxide adducts, sucrose fatty acid esters, fatty acid esters, fatty acid glycerin monoesters, and alkylamine oxides. Among these surfactants, alkylbenzene sulfonates, alkyl ether sulfates, olefin sulfonates, alkanesulfonates, polyoxyethylene alkyl ethers, and polyoxyethylene alkylphenyl ethers are particularly preferred.

The surfactant is usually incorporated in the detergent composition in an amount of 5 to 70% by weight, preferably 10 to 40% by weight.

The hydrogen atom bonded to the nitrogen atom in (b) or the amino-modified silicone used in the present invention is an acyl group having 7 to 24 carbon atoms (which may have a polyoxyethylene chain in the acyl group chain). ) is an amino-modified silicone aridide having a structure simulated by When the number of carbon atoms in the acyl group is less than 7, a sufficient effect of preventing felt shrinkage cannot be obtained.

As such amino-modified silicone amidated products, compounds represented by the following general formula (1) are preferred, and in particular those having 1 to 30 moles, preferably 1 to 10 moles of polyoxyethylene chains in the acyl group chain are preferred. It is desirable because it has excellent effects. [In the formula, R: an alkyl group having 1 to 4 carbon atoms, a hydroxy group, an alkoxy group Rl: an alkyl group having 1 to 4 carbon atoms, each of which may be different A: Rχ t -(Cut)m-N -8 or, where a, b; integers Rt, RS of 2 to 6, preferably 2 to 3;
*B indicating a hydrogen atom or an alkyl having 1 to 4 carbon atoms; C (CHz)c(CJ-0)t R
a110, where c; an integer of 1 to 6, preferably 2 to 4 d: 0 to 30
, preferably from 1 to 30, particularly preferably from 1 to 10. Integer R4: represents an alkyl group having 6 to 18 carbon atoms. ] The molecular weight of the silicone compound represented by the above general formula (1) is 2000 to 150000, and the amine equivalent is 1000 to 2.
A range of 0000 is preferable, and 0 and n are numbers corresponding to these.佽）Ibun is blended in the composition in an amount of 0.05 to 5% by weight, preferably 0.1 to 3% by weight. Incidentally, silicone compounds typified by dimethylpolysiloxane have conventionally been commonly used as foam control agents. Furthermore, JP-A No. 60-215099 describes that flexibility can be imparted to clothing by incorporating a small amount of ξ-anomodified silicone or its derivatives into detergent. However, the amino-modified silicone amides used in the present invention are different from these silicone compounds conventionally used in detergent systems both in structure and effect.

The remainder of the composition of the present invention is fillers such as water and mirabilite.
Other optional ingredients that are included in this type of light detergent may be included. Such optional agents include recontamination preventive agents such as polyacrylic acid, polyvinylpyrrolidone, polyethylene glycol, and carboxymethyl cellulose; enzymes such as protease, amolase, reverse, and cellulase; enzyme stabilizers such as calcium chloride; and ethanol. Lower alcohols such as benzenesulfonates, P-}luenesulfonates, and other lower alkylbenzenesulfonates; Glycols such as propylene glycol; Benzoates, solubilizers such as urea; t-butylated hydroxytoluene, distyrene Antioxidants such as cresol; other fluorescent dyes,
Examples include blue tinting agents, fragrances, antibacterial agents, and the like.

Further, it is desirable that the composition of the present invention does not substantially contain any ordinary detergent builders, but if it contains no more than 2 to 3% by weight of builders such as diglycolates, phosphates, carbonates, etc. It can also be blended.

The concentration of each detergent was 0.25% by weight, and the water temperature was 20°C. For rinsing, the first rinse was done with running water in a pot, and the second time was with running water in a hand washing tub. Next, this sample fabric was applied to the wall of the dehydration tank of a washing machine to dehydrate it for 30 seconds, then placed on a net to dry flat, and the humidity was controlled at 20''C and 65% RH for over 4 hours.

Furthermore, the length between the marks made in (1) was measured again (vertical al'+ a!W; horizontal b,',
